Title: Production of a new rubber sheeting specially for use in the manufacture of boots, shoes or the like
IPC: C08J9/00
Filed: 1926-12-07
Abstract: 288,354. Broomafield, H. Dec. 7, 1926. Indiarubber compositions.-A non-permeable cellular sheet material suitable for the manufacture of boots &c. consists of raw rubber, fillars such as ground vulcanized rubber, lithopone, zinc oxide, vulcanizing agents, and fibres, with a cell producing agent such as water, ammonim carbonate &c. the mix being compounded without the use of naphtha or other softening agent which causes rupture of the cells. A suitable composition consists of 8 lbs. of rubber, 2 lbs. 8 ozs. of lithopone, 8 ozs. of zinc oxide, 4¢ ozs. of sulphur, 5 lbs. of fibre to which is added 10 per cent. of water. An accelerator is added, the mix is sheeted, and vulcanized at atmospheric pressure at 90‹-120‹ C. The amount of water may be varied to vary the cell formation, the moisture naturally absorbed from the air being sometimes sufficient, or rubber direct from the washing mill or an aqueous rubber paste may be used. The vulcanization may take place in stages, for example a smooth or embossed surface may be formed in a vulcanizing press, and the vulcanization completed without pressure. A film of unvulcanizable rubber may be super. imposed before, during, or after vulcanization. A hard wearing surface may be obtained by moulding a rubber mix, pressing it into contact with the vulcanized cellular sheet, with or without a film of a vulcanizable solution, and press vulcanizing the two sheets together. The cellstructure of the first-made sheet is not destroyed by the second vulcanization.

Abstract: 837,140. Ion sources. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 16, 1958 [Oct. 11, 1957], No. 31903/57. Class 39(1). A mass spectrometer ion source, suitable for use with gaseous samples such as uranium hexafluoride, includes an electrode 5 having a base or two similar and parallel upstanding walls defining a path for an ionizing electron beam 12, each wall having therein a series of apertures occupying the major part of the surface area of the wall, so that the electrode has a small surface area whilst providing for a uniform electric field along the path of the ionizing electron beam where it traverses a molecular flow beam of the sample to be ionized. The reduced surface area of the electrode 5 together with concentration achieved using molecular beam flow, limits the amount of adherence by traces of the sample on the walls of the source and thus the memory effect is reduced and the life of the ion source is increased. The sample to be ionized enters the source through an aperture 6 having a diameter equal to or less than its length, from a tube of the same diameter, to promote molecular beam flow.
